my pr5check out the NEW MSP in the backround of the first picture. This is an old picture of my silver beauty.

I would check to make sure the FMU is installed properly(not doubting your skills), If it is, I would check the inernals and make sure there are no internal failures or vaccum leaks. Good luck

So you are running lean in boost, not rich. I'm assuming you installed a FMU, or did your kit come with a piggyback fuel computer? If you have neither, then there is your problem. But if you have one or the other, you might want to check your rise rate on the fmu or play with the fuel computer's...

Forgive my ignorance with the es kit, but how do you know how rich you are running? The narrowband o2 sensor you have probably tapped into was not designed to read that nice 12/1 ratio you probably desire. If you are using a wideband sensor forgive me. When boosting with a narrowband sensor you...

The culprit was originally the fuel pump. While replacing the fuel pump, the battery was disconnected for a considerable amount of time. The culprit was in fact the s-afc. It had reset the to a 6cyl car and was throwing my ecu for one hell of a ride. One minute pegged rich the next almost no...

I'll have to pull the ecu and figure out what's going on. This has been on my car for about 15 months and I've put on about 18,000 boosted miles. The obd-ll problem has been a problem since day one. Very well could be part of the issue. I'll post back tomorrow. Thanks for the reply's so far

I can't hook up my car on an obd-ll scanner. Something got screwy when the turbo was put on. I do have an o2 signal modifier and that could have screwed with the ecu or could very well be the problem(uhm)????? I'm a bit lost at this point, I probably need to take another look at it tomorrow when...

There have been some issue's with the e-manage working on speeds, but I believe they got it to work with the o2 signal modifier or some other voltage clamp. NAPMSP is buying the e-manage for his speed and I'm getting one for my boosted pr5. Very cost efficient and a nice addition to anyone's...

sounds to me like it's your bov. Mine does the same thing. Your MAF sensor is reading one thing and with the bov open it is releasing some of the air that you MAF has calculated therefore shutting your engine down or ruff idle depending on how much air is escaping. You can get around this if you...

cel is on, I've reset this numerous times. It comes on when the blow off valve is open at idle, which in turn causes poor idle when engine is warm. I've yet to recirculate the BOV, I guess I'm somewhat lazy even though I hate to admit it. It has come on now because of the poor fuel conditions.

I'll try that, just need to scrounge some dough for the FPR. Any suggestions, I was thinking about the AEM FPR, but have not decided as of yet.

yp5, my only guess with that is it was in limp mode before the fuel pump replacement. Maybe something else fuel related went awnry with the factory fuel pump, or maybe it was that pos fmu

sorry for any confusion, napmsp is a coworker and had his login remembered.

Here's the symptoms. Upon cold start A/F is pegged rich. primary o2 sensor is actually reading 5.115 volts. Normal readings on cold start would be lean and voltage would read .030 or so. Since the fuel pump upgrade, the above is still a factor, now once warmed up the A/F will read a little above...

I've had two factory fuel pumps go out in the last 4,000 miles. Last night I installed the walbro gss342 in tank fuel pump. BTW, all this was going on before the fuel pump swap and I thought it was the culprit. Here's a few questions, My car is stuck in limp mode when cold(first thing in the...
